1941 Principia

Almost three years after the release of their multiple award winning 1941 Remontoire Bart and Tim Grönefeld are pleased to reveal their first automatically wound timepiece the “1941 Principia”.

The 'Philosophiæ Naturalis Principia Mathematica' often referred to as simply the Principia, is a body of work by Sir Isaac Newton, delivered in three books. Written in Latin, the Principia formulated the laws of motion and universal gravitation. This Newton's scientific study is the foundation of classical mechanics and it led the Horological Brothers to select the 'Principia' name for their first watch with automatic winding mechanism.
